+<description>
+ <para>Specifies which transports and ports the client should try to connect to for SMB traffic.</para>
+
+ <para>The order matters as they are tried in order with short delays for the fallbacks.</para>
+
+ <para>The transport 'tcp' uses raw tcp with a 4 byte length header per SMB PDU.
+ The default port for 'tcp' is 445. Other ports can be specified by adding it
+ after ':', e.g. 'tcp:1445'.
+ </para>
+
+ <para>The transport 'nbt' uses netbios framing on top of tcp per SMB PDU.
+ The default port for 'nbt' is 139. Other ports can be specified by adding it
+ after ':', e.g. 'nbt:1139'.
+ </para>
+
+ <para>Numerical ports are handled as 'tcp' except port '139' is handled as 'nbt'.
+ </para>
+
+ <para>Note that's currently a limit of 10 unique transports, all others will
+ be ignored.</para>
